I can definitely understand where you are coming from, but hopefully there's an "aha" moment with this successful film that Warner/DC will take something away from.
I hope so too. I love DC more than Marvel, so I hope Warner Bros. can pull it together. Disney is eating their lunch right now.
Why not take a page from the DCAU? Bruce Timm and company managed to make some awesome TV episodes and movies in the DC universe by honoring the source material, casting well, and developing their characters.
